Ok all the links are back in and I ve put a link between the SAB terminals T and A (you were right ).

The alarm is still not unlocking after power up. After 'user reset' following putting the panel back on, the 'tool' LED is flashing and the "SOS' LED is on permanently.

Any thoughts?

Cheeers !

you hold the spring tamper down too ?

yep

then you may have a voltage issue.have you disconncted everything?

No, the PIR's are still connected as are the door contacts on the relevant zones

dis everything from the tamper circuits. Even with a link if you have a positive voltage into those connections it will cause a tamp fault even with a link

Ah no, nothing other than the links are connected on the tamper circuits. The PIRs and contacts are only connected to the zones (i.e zone 1 + 2 contacts), (3+4 for PIRs + supply power). All the other zones (5-8) are linked out.

Could there still be a voltage issue?

TRY IT LIKE THIS, TAKE EVERYTHING OUT.

E V E R Y T H I N G

CONNECT ONLY O N L Y THE KEYPAD

YOU ARE TRYING TO PROVE THE PANEL, SO IT NEEDS EVERYTHING DISCONNECTED.

PUT THE KEYPAD ON A SHORT FLYLEAD, THAT YOU KNOW IS NOT DAMAGED.

Do you think I said this twice before because I have nothing better to do??

it does sound like the board may be goosed but as oxo say its best to try with everything dissed. If its an optima then also drop the keypads and just see if it works with nowt connected. and all links in place. If it dont then its gone. But id be suprised they have a very low failure rate

It doesn't have a keypad, its built in, but you what tomorrow, I might just take everything out....

mate !
